Illustrate the mass spectrum of ammonia (gas) ionized by electron impact (EI) using 70 eV electrons
and Illustrate the spectrum for 12 eV electrons.
What form of NMR might be used to characterize ammonia?
Illustrate and label the NMR spectrum and list some of the principal characteristics of NMR spectroscopy as a qualitative and quantitative analytical method

I wrote it is a 5 membered ring with double bond on two sides but
it is incorrect

Electrons in an electron microscope have a kinetic energy of
1.20 105 eV. (a) Find the de Broglie wavelength of the electrons.
Incorrect: Your answer is incorrect. (b) Find the ratio of this
wavelength to the wavelength of light at the middle of the visible
spectrum (550 nm). (c) How many times greater magnification is
theoretically possible with this microscope than with a light
microscope?

Gas phase transition metals, when ionized, lose their
s-electrons first and the remaining electrons redistribute
themselves in the d-orbitals (with some exceptions as discussed in
class). To understand this phenomenon, calculate the Zeff for the
4s and 3d-electrons separately for the following atoms: Sc, Ti, V,
Mn, Fe and Ni. On the basis of the Zeff, which of the electrons (4s
or 3d) would be removed first? Ionize each of these atoms to their
monopositive ions (i.e. Ti to Ti+...

Consider a neutral plasma (a gas of electrons and positive ions)
with electron density n. At high frequencies, because the ions are
very heavy, we can consider them to be essentially fixed and any
current due solely to the much lighter electrons. The total charge
density can be set to zero for an electrically neutral gas. If E(t)
= E_0*e^(-iwt), use Newtonian physics to find the current density
J(t) in terms of w (omega), n, E(t), and the electron mass...
